If you download the IRS instructions they lead you through a complex calculation which ends up by saying basically that if you paid estimated taxes on time and paid enough you don't submit the form. That path is not currently in Turbotax, and presumably will be implemented by the upcoming fix, but basically gets spoofed by the workarounds. Turbotax correctly handled form 2210 last year so it's kind of hard to see how tax changes are at issue. Form 2210 is the IRS answer to punishing you for not being omniscient. since, clearly, you should pay estimated taxes of the proper amount, at the proper rate, and at the time you earned the income and should know all of your income sources a year in advance. Of course this really only works for salaried people with no variable supplements. If Turbotax didn't handle the complex cases like this, (it used to) there would be no need to subscribe to it.
